STM32F777VIT6 - 216MHz Cortex-M7 MCU | STMicroelectronics
MPN: STM32F777VIT6 ✓ AktifSTM32F777VIT6 Genel Bakış
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and communication interfaces on one device. The STM32F7 family belongs to the Arm Cortex-M product hierarchy, where the STM32F777VIT6 combines a 32-bit RISC core, embedded Flash, SRAM, timers, serial controllers, and GPIO. This integration reduces system complexity by placing control, data acquisition, communications, and real-time processing within a single package.
The STM32F777VIT6 reaches a maximum core frequency of 216 MHz and provides 2 MB of Flash plus 512 KB of SRAM. Its timer configuration includes as many as 18 timers, including up to 13 16-bit timers, two 32-bit timers, two watchdogs, and the SysTick timer. According to the STMicroelectronics datasheet, all 15 main timers can operate at up to 216 MHz, supporting precise timing, motor control, signal generation, and industrial automation functions.
The device uses the Arm Cortex-M7 architecture with single-precision floating-point capability and a high-performance instruction set suited to control loops and digitally assisted signal processing. Dual-mode Quad-SPI support is also identified in the product documentation. These resources allow software to handle communications protocols, data acquisition, and control algorithms without relying on multiple discrete processing components.
Typical uses include industrial motor controllers, factory automation nodes, high-performance human-machine interfaces, embedded audio equipment, communications gateways, and sensor-processing systems. The 100-LQFP package is particularly appropriate for prototypes, industrial controllers, and medium-complexity boards where a large pin count provides access to peripherals while remaining compatible with conventional leaded-package assembly processes.
Power-supply design should preserve clean, stable rails for both the core and I/O domains, while high-speed communication interfaces require controlled impedance routing and short return paths. Firmware should also account for internal versus external clock selection, flash wait-state configuration, peripheral clock enablement, and the device-specific startup sequence described in the manufacturer reference manual.
This product page combines core specifications, same-footprint replacement options, interface-oriented application guidance, and practical design cautions. It is intended to accelerate engineering evaluation while directing pin assignments, firmware support, and assembly decisions back to the authoritative STMicroelectronics datasheet and reference documentation.

Tasarım Notları
Design the power tree around the exact STM32F777VIT6 supply pins and voltage domains listed in the manufacturer pin table. Separate analog, digital, and I/O supply paths where the device architecture permits, and place local high-frequency bypass capacitors directly beside the relevant pins. Validate startup current, regulator headroom, and load-transient behavior at the 216 MHz operating point. Do not infer acceptable rail tolerances from a generic STM32F7 board because package-specific pin assignments and application notes remain controlling.
Treat clock configuration as part of the power, timing, and EMC design rather than a late firmware task. The STM32F777VIT6 can operate at up to 216 MHz, so the external crystal or clock source, PLL settings, flash wait states, and peripheral clock tree must be initialized in the documented order. Keep the oscillator path away from high-current switching nodes and sensitive analog inputs. Confirm startup behavior across the full intended temperature range because oscillator accuracy and startup margin affect UART, USB, and time-sensitive interfaces.
Use the exact 100-LQFP land pattern and pin numbering from the STMicroelectronics package drawing. A 14 x 14 mm leaded-package footprint requires careful paste and solder-fillet design, and pin 1 orientation must be checked against both the PCB silkscreen and the component marking. Although the package is not extremely dense, its 100 leads can create long return paths if the ground and power connections are not planned carefully. Confirm assembly clearance, courtyard, and solderability with the selected board manufacturer.
Route high-speed communications and memory signals with continuous reference planes and avoid splits in the underlying power or ground structure. Although the STM32F777VIT6 is a microcontroller, several communications interfaces can operate at frequencies that make return-path discontinuities and crosstalk important. Keep external clocks, communications lines, and sensitive analog inputs separated from switching-power inductors and high-current traces. Apply the device-specific capacitance and routing guidance in the manufacturer reference manual to each external interface.
Do not treat a shared package as proof that every alternative has identical behavior. For each proposed substitution, compare the ordering-code temperature grade, memory configuration, peripheral mapping, clock limits, pin electrical characteristics, and supported development software. If an alternative changes only a qualification suffix, update production inspection and documentation records. If the family member changes peripheral emphasis, review the complete pin and alternate-function tables before committing the component to a release.
Uyumluluk Bilgisi
The manufacturer product page and family datasheet identify the STM32F777xx device, but the product listings do not state the requested compliance classifications. Verify RoHS, REACH, automotive qualification, lead-free, halogen-free, and conflict-minerals status against the current manufacturer product documentation before production release.
